Summary notes of the LCU meeting on 19/04/2013

Present: FB, HB, RDM, LD, SF, MHF, MG, JJ, EM, MS, RT, RV, FZ

Report from meetings

• SLM and general information -> MG
  Massimo reminded us about the IPAC dealines which were also send by email. HL-LHC related papers with FP7 support should include an acknowledgement. The internal approval is the same as for the other IPAC'13 papers.
  Fellow planning was discussed for ABP. The request for a fellow for re-comissioning will be postponed to next year. The planning has one fellow for LHeC.
  As said before a general group meeting with BBQ is planned for the 19 June.
• MAD-X status -> LD
  Laurent said that there was a lot of activity recently and that many changes were commited to the repository. Automatic testing on the recently purchased iMac will soon become available once that the windows license issues have been clarified. A garbage collector is planned for the release next week. Frank Schmidt is working on space charge code. Laurent plans for a new pro-release soon.
  Andrea Latina works on the documentation for thick quadrupole tracking. A first draft version will soon be forwarded to our local experts. Ghislain found a bug in the aperture model related to rectangular apertures. John reminded about the importance of rectellipse for the LHC apertures.
• SixTrack status -> RdM
  Xavier Barranco became fellow in ICE and will look at the beam-beam lens for SixTrack. Stephane asks that the code shoudl be checked for the flat beam-beam lens. The FLUKA team uses SIXTRACK with modifications for the SPS to simulate fast kicker changes. The modifications should be included in the main trunk of SIXTRACK. Matthias builds test cases for the exact Hamiltonian and plans to check the effect for smaller machines like LEIR and PS. The work on more documentation is in progress.

Upgrade of makethin -> HB (slides)

Helmut reminded about the sucessful extension of TEAPOT slicing to more than 4 slices and presented plans to further extend the functionality of makethin in several respects :

selected slicing on/off, thick quadrupoles, automatic bend translation with separation of fringe fields. For details see the slides. He started on the implementation of these feastures and has now a "alpha"-test version for first feedback.  He showed as one example the automatic dipedge generation in dipole slicing applied to LEIR.
There appeared to be a strong interest in these new features. Helmut received many constructive comments and feedback on this subject.
